ReviewSpinal brucellosis: Turkish experience based on 452 cases published during the last century.
Spinal brucellosis continues to be the leading cause of morbidity from infectious disease in the infested regions of the world, particularly in the rural areas including Turkey. The purpose of this review was to present the Turkish experience by analyzing the literature on the management of spinal brucellosis during the last century. ⋯ Based on this critical review of literature from Turkey, it is concluded that early diagnosis and correct management are important to prevent the harmful effects of brucellosis and its complications, and that the treatment of choice is antibiotic therapy alone in most cases of brucellosis involving the spine.

Review Case ReportsThe midline suboccipital subtonsillar approach to the hypoglossal canal: surgical anatomy and clinical application.
Primary lesions of the hypoglossal canal, such as hypoglossal schwannomas, are rare. No consensus exists with regard to the surgical approach of choice for treatment of these lesions. Usually, lateral transcondylar approaches have been used. ⋯ The midline subtonsillar approach permits a straight primary intradural view to the hypoglossal canal. There is no necessity of condylar resections. The surgical anatomy of the subtonsillar approach is described and illustrated by an example of a case.

The world's literature on traumatic brain injury (TBI) grows annually including new reports on epidemiologic findings from many regions. With the wide variety of reports emphasizing various factors it is useful to compile these findings, hence the objective of this report. Thus, we describe epidemiological factors from European studies largely published in the last 20 years. ⋯ It was difficult to reach a consensus on all epidemiological findings across the 23 published European studies because of critical differences in methods employed across the reports. We highly recommend the development of research guidelines to standardize definitional, case finding, and data reporting parameters to help establish a more precise description and hence utility of the epidemiology of TBI in Europe.

ReviewMicrovascular decompression for primary hemifacial spasm. Importance of intraoperative neurophysiological monitoring.
There is considerable evidence that primary Hemi-Facial Spasm (HFS) is in almost all cases related to a vascular compression of the facial nerve at its Root Exit Zone (REZ) from brainstem, and that Micro-Vascular Decompression (MVD) constitutes its curative treatment. Clinical as well as electrophysiological features plead for mechanisms of the disease in structural lesions at the neural fibers (putatively: focal demyelination at origin of ephapses) and functional changes in the nuclear cells (hyperactivity of the facial nucleus). Lateral Spread Responses (LSRs) elicited by stimulation of the facial nerve branches testify of these electrophysiological perturbations. ⋯ MVD allows cure of the disease in most cases. Because the VIIIth nerve is at risk during surgery, intraoperative monitoring of Brainstem Auditory Evoked Potentials (BEAPs) is of value to reduce occurrence of hearing loss. Increase in latency of Peak V and decrease in amplitude of Peak I are warning-signals of an excessive stretching of the the cochlear nerve and impairment of the cochlear vascular supply, respectively.

Review Case ReportsSpinal subarachnoid hematomas: our experience and literature review.
Spinal subarachnoid hematomas are unusual and difficult to diagnose and the outcome of treatment is influenced by the lesions that frequently accompany them. ⋯ MRI and CT are not usually diagnostic because they are not able to differentiate between a subarachnoid lesion and a subdural one. However, diagnosis may be possible when these investigations detect the CSF or the contrast medium surrounding the hematoma. Although the risks of producing spinal subarachnoid hematoma as a result of LP are remote, this is, in fact, the primary cause in patients with coagulopathies. The results of treatment depend on the patient's initial neurological condition, the severity of any concomitant pathologies, the position of the hematoma and the eventual association of a subdural hematoma.
